  • Compare FGS mtdna against Neandertal

    BLAST your FGS mtdna against Neandertal

    Example:
    Neandertal full sequence is NC_011137.
    Human full sequence is NC_012920.

    Go to: http://blast.ncbi.nlm.nih.gov/Blast.cgi, and then select nucleotide blast

    1. select align two or more sequences
    2. paste the NC_011137 in the top box. <- Neandertal mtdna full sequence
    3. paste NC_012920 in the second box (or your full genome accession number, if you've tested with FTDNA and uploaded to Genbank).
    4. click BLAST
    5. Scroll down
    6. See the number of identities:
    16358 out of 16570 or 212 mutations

    My result: 217 mutations
    Neandertal vs rCRS: 206 mutations

    ref
    This paper http://www.ncbi.nlm.nih.gov/pmc/arti...nihms65170.pdf
    found "Alignment of the 16,565 nt Neandertal mtDNA to the 16,568 nt human revised Cambridge reference mtDNA sequence (rCRS) (Andrews et al., 1999) revealed 206 differences (195 transitions and 11 transversions)."

    Interesting!

    My result is 209 mutations.

      The same exercise vs chimpanzee:

      chimpanzee: NC_001644
      human reference: NC_012920

      1061 mutations
      Identities = 12198/13259 (92%)
      (estimated divergence time of 7 million years between chimpanzees and humans)

      my result: 1058 mutations
